HIGH FREQUENCY CIRCUIT

A printed wiring board includes conductor layers, a core layer having an opening, and a build-up layer. A high frequency device placed within the opening is installed such that a mirror surface is thermally connected to a conductor layer for heat dissipation facing the opening from a lower surface s...

Beschreibung
Zusammenfassung:	A printed wiring board includes conductor layers, a core layer having an opening, and a build-up layer. A high frequency device placed within the opening is installed such that a mirror surface is thermally connected to a conductor layer for heat dissipation facing the opening from a lower surface side of the core layer, and terminals on the terminal surface are electrically connected to conductor layers formed on an upper surface side of the core layer.
